      I'm not sure about that...

      Chances are you already have to wait a few seconds for other reasons.
      It is not uncommon, when I haven't done anything for a while, to hear
      my disks for my NSLU2 spin up, by something simple like opening a web
      page in Firefox.

      The reason that happens, is among other things, I have my NSLU2
      configure as a DNS server. Because the NSLU2 has such limited amount
      of ram, eventually after enough idle time, the DNS server process gets
      swapped out to disk. After a while of not using the disks, the USB
      enclosure spins those down. So a few hours later, when I decide to
      use firefox the process is delayed for two seconds while the NSLU2
      spins up the disks and then loads the process back into memory. WOL
      would not add a significant amount of additional delay to this...
